To all whom it may concern:

Be it known-that I, CHARLES E. POPE, a citizen of the United States ofAmerica, and a resident of Holyoke, in the county of Hampden andStateofMassachusetts, have invented certain new and useful Improvements inCutting, Perforating, and Roll Forming Mechanism, of which the followingis a full, clear, and exact description.

The object of this invention is to produce a new and improved machinewhich will have individually and severally' the capabilities of windingpaper from a supply roll of large diameter and great width into'smallerrolls, as suitable for toilet use; of longitudinally slitting the wideweb running from the supply whereby the lengths of the several toiletpaper rolls wound at one time are but fractional of the length of thesupply web; of providing in the paper, preparatory to the reeling orwinding thereof at suitable regular intervals in its length, transverselines of incisions on which suitable lengths or portions of the rolledtoilet paper may be torn from the roll; of insuring that the-rolls ofpaper wound up in the machine will be all of uniform diametrieal size,and consequently will each be constituted by a predetermined quantity ofpaper, and of insuring that the rolls of paper will have theconvolutions thereof very tightly or quite loosely wound as may bepreferred.

The invention consists in improved paper Winding or roll forming means;in improved means for imparting transverse lines of incisions atintervals in the length of the paper; in automatic mechanism forstopping the roll-making machine so soon as the roll has been wound to arequired diametrical size; in improved means for tensioning the paperwhile being wound and in the general combination and arrangements ororganization of the parts making the machine in its entirety ashereinafter set forth.

The improved machine is illustrated in the accompanying drawings inwhich Figure 1 is substantially a plan view-upper portions of themachine comprising the automatic stop motion not being shown. Fig. 2 isa front elevation. Fig. 3 is a vertical cross sectional view of themachine as taken on line 3 3, Fig. l. Fig. 4 is an end elevation of themachine as seen looking to the rightward from the plane indicated byline 4 4, Fig. 1. Fig. 5 is a sectional elevation as seen looking to theright from the plane indicated by the line 5-5, Fig. 1; and Fig. 6 is aperspective view of one of the round and incised rolls of paper fortoilet or other use.

Similar characters of reference indicate corresponding parts in all ofthe views. l

In the drawings A represents the irame of the machine comprising uprightstandards 10, between which is mounted the axially horizontal cylinderB, herein to be termed the "bed roll, the shaft or arbor of said roll`being extended through, and journal-supported in the said end standardsof the frame and one end journal of each roll is provided with a spurgear wheel 12 and fast and loose pulleys 13 and 14, around 60 either ofwhich the belt 15 may be in driving engagement accordingly as it ispositioned by the horizontally slidable belt shifter 16; and the otherend journal of the bed-roll has the spur gear wheel 17 affixed thereon.

18 represents a support or bracket formed as part 65 of the frame, for acomparatively long andV heavy supply roll 19 of paper.

20 represent-s a small paper guide bar supported by the frame parallelwith, and adjacent the upper rear peripheral portion of, the bed-roll,and 22 represents 70 a cylinder, to be herein termed the speed ortensioning roll axially parallel with, forward of, and about on a levelwith, but slightly peripherally separated from, the bed-roll, and thisroll at the left hand end of the machine is provided with 'a spur gearwheel or 75 pinion 23 of smaller diameter than the bed roll gear wheel17, and driven in the same direction as the bed roll by means of theintermediate or idler gear wheel 24,

(see especially, Fig. Ll). The speed roll77 therefore turns in the samedirection as, but somewhat faster 80 than, the bed-roll, and these tworolls, as perceived in Fig. 3 form a longitudinal cradle on which mayrest the core x for the toilet paper roll, and as the winding progressesfor the building roll y.

Suitably below and to the rear of the bed roll B is a horizontal shaft26 axially parallel with the bed roll, carrying long blades, 27,` 27,edgewise oppositely eX- tended, and which blades are edgewise formedwith V-shaped teeth `2S which in the revolutions of the blades on thesaid rotary shaft 26 may freely enter 90 within, and pass from, thelongitudinally arranged series of recesses 29 29 along opposite sides ofthe bed roll. These toothed revoluble blades form transverse rows ofV-shaped incisions z Fig. 6, in the web, guided to and running partiallyaround the bed roll to be wound on the core x.

The blade-carrying shaft 26 at the right hand end of the machine framehas a spur gear wheel 30 thereon equal in size to, and in mesh with, thebed-roll gearwheel 12 so that the blades are caused to revolve in 100unison with the bed-roll.

Below and slightly forward of the bed-roll is a horizontal shaft 32extending between and journaled in the ends of the frame and havingsuitably spaced slitter disks 33, 33, closely overlapping and co-actingwith shear forming shoulders 34, 34, on the bed-roll.

The slitter shaft 32 extends through and beyond the right hand end framestandard only, and is thereat provided with a spur pinion gear 35 inmesh with the spur gear l2 on the bed-rolL-as well as is theaforementioned gear 30 for the blade carrying shalt. p

The main end standards l0 l0 have supplemental l uprights or standardsll, vll thereabove, having vertical grooves 37 in their inwardly facingsides in which may be engaged end gudgeons oi a weight roll 38 which maybe employed when an extremely dense and closely wound roll ol toiletpaper is to be produced, such roll bearing on the upper side oi thebuildin!r paper roll and c( using it to acquire a more positivelrictional engagement with the rolls on which the building roll issupportcd,-and most effectively on the speed roll 22.

40 represents a rock-shalt, longitudinally supported and ranged abovethe bed-roll, having at or about its middle a forwardly extendingarm-42, provided with a vertically adjustable bar 43 held coniined inany given set position by the screw 44; and said rock-shaft also has arearwardly extending latch arm 45, which is normally in engagement withthe notch 4G in the horizontally slidable bar comprised in` the beltshii'ter 1G. The belt shiiter is held back, that is, to the leitward,with. its spring 48 in compression between the shouder 47 and a portionoi the frame.

The web oi paper iroin the supply roll is drawn in lull width forwardlyover the guide bar 20, under and partially around, and in contact with,the bed-roll and is engaged with a pasteboard core as long as the web iswide, and the machine is set in motion by drawing the bar oi' the beltshilter to the leit, latching it by the rock-bar-arm 45 and holding thedriving belt l5 on the fast pulley. The core and paper engaged therearound will be rotated by the i'rictional engagement oi the periphery oithe bed and speed rolls and will be very satisfactorily tensioned by thelatter, whereby the formation of a loosely wound or flabby roll will bei avoided, and the paper before coming to be wound on the core will havethe transverse rows oi V-cuts Z made therein at proper intervals7 by thetoothed revoluble blades, and will be slitted by the disks ior themaking oi toilet paper rolls oi the proper length. When the paper' hasbeen wound on in sutlicient quantity to make a roll oi' the size wantedthe built roll directly, or

through the weight bar 3S thereon, will engage the bar 43, rocking shalt40 and unlatching the belt shifter 16, so that thespring 48, appurtenantthereto, will react to automatically cause the positioning oi the belton the loose pulley 14, and to cause the stoppage oi the machine so thatthe already wound paper may be removed, and a repetition of thedescribed operations performed.

l. The combination with a recessed rotary bed roll, liav ing circularshoulders, of a revoluble toothed blade coacting with the recessedportion of the roll, and means for rotating it, and a rotary shai'thaving slitter disks coactA ing with the shouldered portion oi the roll,and means for rotating the disk shalt.

2. In a mechanism et the character described, the combination with thebed-roll having a driving pulley at one end, and having a spur gearwheel at each end thereol, et a slitter. disk shaft and an incisionblade shaft, below, axially parallel with, and respectively forward andto the rear of the axis of the bed roll, and having gear wheels at oneend of each, both in mesh with the gear wheel at the corresponding endof. the bedr-ell, and a speed roll, axially parallel with, adjacent andforward oi? the bed roll, having thereon a gear wheel smaller than thegear wheel at the other end ot the bed roll, and an intermediate gearwheel in mesh with the latter bed roll gear and the speed roll gear, forthe purposes set forth.

2i. 'lhe combination with an axially horizontal bedroll and another rolllocated adjacent and at about the level oi' the bed roll, and a pulleyhaving a driving connection with said rolls, and having a driving` belttherefor, oi' a slidable belt-shatter, engaging said belt, a spring forforc- Y ing the latter in one direction and a rock shaft having a latcharm engaging the belt shitter, and having another member extended oversaid rolls, and adapted to be engaged and swung by a roll ol' paper whenwound to a required size.

4. The combination with an axially horizontal bed-roll, a speed rolllocated adjacent and at about the level of the bed roll, and a pulleyfixed to the bed-roll, and a loose pulley alongside the fixed pulley, ashiftable belt to run around either oi' said pulleys, a slidableshii'ter Vfor said belt, having a spring for forcing it in onedirection, and gear wheel connections between the bed and speed rolls,lor driving the speed roll faster than the bed roll. oi a rock shafthaving a latch arm engaging the belt shifter, and having another armradially projected at a location above said rolls and provided with avertically adjustable bar, i'or the purposes set iforth.
